STENCILING DEVICE.

Application filed May 29, 1926. Serial No. 112,567.

This invention relates to a stenciling device and particularly relates to 'means for applying stencil work to walls and other plane surfaces. i i

It is common practice in applying conventional designs to plane surfaces touse a' stencil and apply paint or other coloring material to the surface with a brush through the openings, after which the stencil must be reset and the painting operation continued. This requires considerable care in setting and removing the stencil as well as applying the paint and it is the object ofthe present invention to provide means whereby a conventional design may be progressively applied to a surface'through a stencil and the paint or other coloring material automatically forced through the stencil and onto the surface to be painted. The present invention contemplates the use of a stencil, the openings in which are covered by a thin sheet of foraminous material and through" which the paint or other coloring pigment may be forced onto the surface, said stencil in the present instance beingin the form of a drum adapted to rotate as the structure is moved along the surface to receive the design, the drum forming a container for the supply of the paintand carrying means for forcing the paint through the mesh of the screen in the stencil.

The invention is illustrated by way of example in the accompanying drawing in which:

Figure 1 is a view in transverse section through the stencil structure with which the present invention is concerned.

Figure 21is a view in end elevation-showing the stencil structure with parts broken away. v

Figure 3 is a side view in elevation showing the stencil structure partly in elevation and partly in central longitudinal section.

Figure 4 is a view in plan showing the stencil structure partly in elevation and partly in central longitudinal section.

Figure 5 is an enlarged sectional view through the stencil.

Figure 6. is an enlarged fragmentaryview showing a portion of the stencil.

Referring more particularly to the drawings, indicates a shaft secured at its opposite ends within bearing plates 11 and 12 by wing nuts 13. The bearing plates stand parallel to each other and as shown in Figs. 1 and 2, are intended to stand at right angles to a surface 14 upon which a design is to be applied.- The shaft 10 carries a stenciling drum 15. This drum comprises disk-shaped heads 16 and 17 formed with elongated hubs 18 and 19 respectively. The shaft 10 extends through the hubs and permits free rotationof the hubs and headsthereon. The contiguous ends of the hubs are spaced a distance from each other to receive a collar 20, which carries a squeegee blade 21 mounted thereon by a centrally disposed hinge 22. This blade is'clamped into position between clamping'plate's 23 and 24 secured together by screws 25. The blade 21 extends parallel to the shaft 10 and is adapted to bear against the inner surface of a cylindrical stencil 26 mounted upon the drums 16 and 17 and spanning the distance therebetween. This stencil is fitted with hubs 27 which secure it around the circumferences of the heads 16 and 17. The stencil is formed with a foraminous backingsuch as fine screen'wire and over which the usual stencil structure may be stretched.- It is also within the contemplation of the present invention toform conventionaldesigns by blocking out or closing the mesh 1n certain areas of the screen to prevent the paint from passing through separate from each other and are freely stencil drum 26. This has been done in thepresent instance by forming a gear 28'.

.around the edge of each of the heads 16 and quantity of ink, dye, or plate is placed within the cylindrical stencil by removing one of the plates 11- or 12 from the connecting frame member 31. This may be readily done by unfastening the wing nu'ts32, which hold the plate against the connecting frame member 31 and removingone of the wing nuts 13 from the end of the shaft 10. One of the drums may then be removed by loosening the screws 33. After a suitable amount of paint or other material has been placed Within the drum, the head may be replaced and the end plate again fastened in position. It is' only then necessary to move the device along the surface 14 to be stenciled, during which time the structure is resting'against the surface at a point lengthwise of the drum and also upon rollers 34 carried by the end plates 11 and 12. The drum will frictionally engage the surface and as the structure advances in the direction of the arrow 11 indicated in Fig. 1, the squeegee 21 will tend to bear against the back surface of the stencil 26 and force the paint through the unobstructed mesh portions of the cylindrical screen and onto the surface being stenciled. Due to the fact that the squeegee is mounted upon a hinge 22, it will be evident that the squeegee may swing backwardly and adjust itself to the quantity of paint within the drum. It will thus be seen that by the construction here shown, 'it is possible to rapidly and accurately produce and reproduce a conventional design upon a plane surface by simple and inexpensive means.

While I have vshown the preferred form of my invention as now known to me, it will be understood that various changes might be made in the combination, construction and arrangement of parts by those skilled in the art without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim is:

1. A stenciling device comprising a cylindrical container adapted to contain stenciling material, a stencil forming one wall of said container, and a moving blade arranged within the container and. adapted to be moved over the inner surface thereof as the container revolves to cause the material withinthe container to'be forced through openings in the stencil.

2. A device of the character described comprising a cylindrical stencil, means supporting said stencil while permitting it to move along a plane surface to be stenciled, and means within the cylindrical stencil for applying and causing marking material to be forced through the openings in the stencil as said cylinder rolls along the surface to be stenciled.

3. A stencil device comprising a frame, a cylindrical stencil rotatably mounted upon said frame and adapted to roll along a plane surface as supported by the frame, said cylindrical stencil serving as a container for marking material, and a marking material applying member disposed in the stencil and adapted to force the marking material through the openings in the stencil as the stencil rolls along the plane surface.

4. A device of the character describe-d comprising a frame structure adapted to move along a plane surface, a cylindrical stencil carried thereby and adapted to roll along the plane surface, said stencil comprising a cylindrical screen, separate heads mounted in the opposite ends of said screen, a shaft carried by the frame upon which said heads are freely rotatable, a paint applying blade suspended upon the shaft between the heads,

and means for causing said heads to rotate in unison upon the shaft.
